目的:了解黑龙江省农村地区翼状胬肉的患病率及相关危险因素。
  方法:以人口为基础的横断面研究,在黑龙江省明水县整群随机抽取35个行政村为调查点,抽取50岁以上人群共6196名作为调查对象。研究该人群分布特征和翼状胬肉的患病率、分布特征、危险因素。
  结果:在50岁以上人群中,实际接受检查5669名,受检率91.49%。发现翼状胬肉患者246例329眼,至少有1眼患病的患病率为4.34%;翼状胬肉的患病率与年龄正相关(年龄每增加10岁,OR=1.616,95%CI:1.372~1.903, P<0.01);Logistic回归分析结果表明,外出不配戴眼镜与配戴眼镜相比,OR=5.045,95%CI:1.592~15.985,P=0.006;平时工作活动地点在室外与室内工作者相比, OR=3.896,95%CI:2.834~5.356,P<0.01;平时外出或室外娱乐的时间>4h 与<4h 相比,OR=1.410,95%CI:1.064~1.869,P=0.017;翼状胬肉的发生与年龄、是否配戴眼镜、户外工作的时间相关。
  结论:在高寒地带的黑龙江省农村地区翼状胬肉患病率有所下降。高龄、户外工作是其危险因素,而外出时配戴眼镜是其保护性因素。  相似文献

PURPOSE: To investigate the prevalence and risk factors of correctable visual impairment and the quality of life of persons with correctable visual impairment in a metropolitan senior population. METHODS: The study was a community-based, cross-sectional survey of vision and eye diseases among noninstitutionalized subjects aged 65 years and older in the Shihpai community of Taipei, Taiwan. The study consisted of a structured questionnaire followed by a comprehensive standardized ophthalmic examination included presenting and best corrected visual acuity, tonometry, slit lamp biomicroscopy, and direct and indirect ophthalmoscopy. RESULTS: A total of 1361 subjects (response rate, 66.6%) participated in both completion of the questionnaire and ophthalmic examination. The prevalence of correctable visual impairment (presenting visual acuity in the better eye <6/12 that improved to no impairment [>/=6/12] after refractive correction) was 9.55% (95% confidence interval [CI], 7.97%-11.13%). Under multiple logistic regression analysis, older age (>/=75 years; odds ratio [OR], 2.41; 95% CI, 1.56-3.70) and nonemmetropic eyes (myopia; OR, 6.80; 95% CI, 3.77-12.77 vs. hyperopia; OR, 2.13; 95% CI, 1.29-3.51) were significantly related to correctable visual impairment. A higher level of education (OR, 0.52; 95% CI, 0.32-0.83) and wearing distance eyeglasses during the eye examination (OR, 0.23; 95% CI, 0.12-0.43) were protective factors for correctable visual impairment. Subjects with correctable visual impairment scored significantly lower in the physical functioning dimension of the SF-36 questionnaire (P < 0.001). CONCLUSIONS: The results demonstrate that approximately 10% of the senior population in the Shihpai district has a correctable visual impairment. Thus, it is important to educate the public about the importance of regular examination and the possibility of improving visual acuity by wearing glasses.  相似文献

Purpose

To evaluate the incidence of symptomatic dry eye disease (SDED) and associated risk factors in a well-characterized cohort of ethnic Malays in Singapore.

Methods

We included 1682 participants (mean age [SD]: 57 [10]years; 55.4% female) without SDED from the Singapore Malay Eye Study (SiMES), a population-based longitudinal study with baseline examination (SiMES-1) conducted between 2004 and 2006, and follow-up examination (SiMES-2) conducted between 2010 and 2013. SDED was considered to be present if a participant answered “often” or “all the time” to any of the six questions from the Salisbury Eye Evaluation Study dry eye questionnaire. Age-standardized incidence of SDED was calculated as the crude 6-year cumulative incidence standardized to Singapore's population census. Gender-stratified multivariable log-binomial regression models were utilized to determine the independent risk factors of incident SDED.

Results

At the 6-year follow-up, 86 of 1682 participants had developed SDED, which was equivalent to an age-standardized 6-year incidence of 5.1% (95% CI 4.1–6.4%). There were no differences in the incidence of SDED between men and women (P = 0.9). Multivariable models revealed that presence of glaucoma and poorer self-rated health were independently associated with incident SDED in men (P = 0.003 and 0.03, respectively), while contact lens wear (P = 0.002), history of thyroid disease (P = 0.03), and having had cataract surgery (P = 0.02) were predictive of incident SDED in women.

Conclusion

One in twenty adult Malays developed SDED over a 6-year period. Risk factors for incident SDED were different between men and women. Future studies and public health interventions should consider this gender-specific difference in risk factors.  相似文献

Purpose

A review of ocular surface and meta-analysis of tear stability (tear break up time, TBUT) and tear secretion (Schirmer test) values in healthy children was conducted.

Methods

Articles published between 1996 and 2017 indexed on MEDLINE, PubMed, Embase, Scopus and Google Scholar were retrieved using defined search terms. Statistical analysis (including sensitivity analysis and meta-regression) was performed.

Results

23 studies were summarised (5,291 participants; neonates (0–29 days), infants (1 month - 1 year) or children (1–18 years) and a meta-analysis conducted using 15 eligible studies (1,077 participants). The combined mean TBUT in children was 14.64?seconds (s) (95% CI, 11.64, 17.64) and 21.76?s (95% CI, 20.43, 23.09) for sodium fluorescein TBUT and non-invasive TBUT respectively (NIBUT). The combined mean NIBUT was 32.5?s (95% CI, 31.78–33.22) in neonates. The combined mean Schirmer I with and without anesthesia were 16.26 mm/5?min (95% CI, 13.17, 19.36) and 29.30 mm/5?min (95% CI, 27.65, 30.96) in children and 9.36 mm/5?min (95% CI, 6.54, 12.18) and 17.63 mm/5?min (95% CI, 12.03, 23.23) in neonates. Meta-regression showed a significantly lower TBUT in children from studies conducted in Asia (p?=?0.004).

Conclusion

There is paucity of data on ocular surface variables in healthy children, making it difficult to draw valid comparisons with adult values.  相似文献

AIM: To investigate the risk and protective factors associated with the retinal nerve fiber layer defect (RNFLD) in a Chinese adult population. METHODS: This study was a cross-sectional population-based investigation including employees and retirees of a coal mining company in Kailuan City, Hebei Province. All the study participants underwent a comprehensive systemic and ophthalmic examination. RNFLD was diagnosed on fundus photographs. Binary logistic regression was used to investigate the risk and protective factors associated with the RNFLD. RESULTS: The community-based study included 14 440 participants. There were 10 473 participants in our study, including 7120 males (68.0%) and 3353 females (32.0%). The age range was 45-108y, averaging 59.56±8.66y. Totally 568 participants had RNFLD and the prevalence rate was 5.42%. A higher prevalence of RNFLD was associated with older age [P<0.001, odds ratio (OR): 1.032; 95% confidence interval (CI): 1.018-1.046], longer axial length (P=0.010, OR: 1.190; 95%CI: 1.042-1.359), hypertension (P=0.007, OR: 0.639; 95%CI: 0.460-0.887), and diabetes mellitus (P=0.019, OR: 0.684; 95%CI: 0.499-0.939). The protective factors of RNFLD were visual acuity (P=0.038, OR: 0.617; 95%CI: 0.391-0.975), and central anterior chamber depth (P=0.046, OR: 0.595; 95%CI: 0.358-0.990). CONCLUSION: In our cross-sectional community-based study, with an age range of 45-108y, RNFLD is associated with older age, longer axial length, hypertension, and diabetes mellitus. The protective factors of RNFLD are visual acuity and central anterior chamber depth. These can help to predict and evaluate RNFLD related diseases and identify high-risk populations early.  相似文献

Purpose: To describe dry eye disease in French elderly subjects. Methods: The Alienor Study is a population‐based study on age‐related eye disease in 963 residents of Bordeaux (France), aged 73 years or more. Self‐reported dry eye disease and use of artificial tears were documented through face‐to‐face interview. Dry eye symptoms were assessed using the Ocular Surface Disease Index (OSDI) questionnaire and tear film stability by tear break‐up time measurements (TBUT). Definite dry eye disease was defined as self‐reported dry eye, confirmed by use of artificial tears and/or OSDI greater or equal to 22. Results: Nine hundred and fifteen subjects, with mean age of 80 ± 4 years, returned the OSDI questionnaire. Of these, 271 (29.6%) subjects reported a dry eye disease and 135 (14.7%) were using artificial tears. An OSDI score > 22 was found in 359 (39.2%) subjects and a TBUT < 5 seconds in 335/746 (44.9%) subjects. Overall, definite dry eye affected 21.9% of subjects and was more frequent in women (27.1%) than in men (13.6%). After multivariate adjustment, dry eye disease was also significantly less frequent in subjects with high educational level (odds ratio (OR) = 0.49, 95% confidence interval (CI): 0.31–0.78 for long secondary school) and more frequent in subjects with ocular hypertension (OR = 1.61, 95% CI: 1.02–2.57) and those using anxiolytics (OR = 1.53, 95% CI: 1.02–2.29). Conclusions: This large observational study confirmed the high prevalence of dry eye symptoms among elderly subjects and confirmed some of the previously identified risk factors (in particular female gender and use of anxiolytics).  相似文献

PURPOSE: To describe the factors associated with symptomatic corneal infiltrates in a postmarket surveillance study of continuous wear contact lenses. METHODS: Patients intending to wear lotrafilcon A lenses continuously for 30 days and nights were registered in a 1-year study at 131 clinical sites. A self-administered questionnaire was used to gather demographic and other data at baseline. The severity of the incidence of corneal infiltrative events during the year-long study was graded by an independent adjudication committee. RESULTS: Of 6245 lens wearers, 163 were reported to have symptomatic corneal infiltrative events (2.6%). In 159 wearers, the infiltrates were judged to be lens-related (2.5%). Age < or =25 years and >50 years was significantly associated with the development of corneal infiltrates (< or =25 years OR = 1.75, 95% CI = 1.24-2.48 and >50 years OR = 2.04, 95% CI = 1.40-2.98). Ametropia of > or =5.00 D was significantly associated with corneal infiltrates (OR = 1.60, 95% CI = 1.08-2.37). Study participants who typically wore lenses for >21 consecutive days and nights were significantly less likely to have infiltrates than those who wore lenses for fewer consecutive days and nights (OR = 0.43, 95% CI = 0.24-0.75). Smoking concurrent with contact lens wear was weakly associated with corneal infiltrates (OR = 1.47, CI = 0.99-2.18). CONCLUSIONS: Patient age, degree of refractive error, and failure to achieve the intended wearing schedule were associated with development of symptomatic corneal infiltrative events.  相似文献

Impact of dry eye syndrome on vision-related quality of life   总被引:4,自引:0,他引:4  
PURPOSE: To evaluate the impact of dry eye syndrome (DES) on vision-associated quality of life. DESIGN: Cross-sectional study. METHODS: We identified 450 participants in the Women's Health Study (WHS) and 240 participants in the Physicians' Health Study (PHS) and sent a supplementary questionnaire asking how much their everyday activities were limited by symptoms of dry eye and to what degree problems with their eyes limited them in reading, driving, working at the computer, their professional activity, and watching television. By design, one-third of study subjects had clinically diagnosed DES or severe symptoms and two-thirds did not. We used logistic regression to examine relationships of DES with reported problems with everyday activities in each cohort and pooled estimates using meta-analysis methods. RESULTS: Of the participants invited, 85% completed the supplementary questionnaire, including 135 WHS and 55 PHS participants with DES, and 250 WHS and 149 PHS participants without DES. Controlling for age, diabetes, hypertension, and other factors, those with DES were more likely to report problems with reading ([odds ratio] OR = 3.64, 95% [confidence interval] CI 2.45 to 5.40, P < .0001); carrying out professional work (OR = 3.49, 95% CI 1.72 to 7.09, P= 0.001); using a computer (OR = 3.37, 95% CI 2.11 to 5.38, P < .0001); watching television (OR = 2.84, 95% CI 1.05 to 7.74, P = .04); driving during the day (OR = 2.80, 95% CI 1.58 to 4.96, P < .0001); and driving at night (OR = 2.20, 95% CI 1.48 to 3.28, P < .0001). CONCLUSIONS: DES is associated with a measurable adverse impact on several common and important tasks of daily living, further implicating this condition as an important public health problem deserving increased attention and resources.  相似文献

AIM: To investigate the association between tear film break up time (TBUT) and blinking interval in visual display terminal (VDT) users. METHODS: Nine hundred and thirty VDT users underwent dry eye testing, and functional visual acuity (FVA) test. The blinking interval during FVA was compared with TBUT. Subjects with longer blinking interval than TBUT were considered as unstable tear film. Logistic regression analysis revealed the risk factors for unstable tear group. RESULTS: Among 930 workers, 858 subjects (92.3%) participated in this study. Almost 80% of the subjects were categorized into the unstable tear group. Unstable tear group has significantly lower Schirmer values and TBUT (17.5±11.6 vs 21.1±11.5 mm, 3.7±2.6 vs 5.7±2.7s, both P<0.001). There were no significant differences in epithelial staining or severity of symptoms. Logistic regression showed that over 40y was a risk for being unstable tear group [odds ratio (OR)=1.53; 95% confidence interval (CI)=1.06-2.20]. Contact lens use was protective factor for being in the unstable tear group (OR=0.37; 95%CI= 0.26-0.53). CONCLUSION: Subjects with shorter TBUT than blinking interval are prevalent among VDT users. Subjects over the age of 40 shows an increased risk for unstable tear film.  相似文献

ABSTRACT

Purpose: The prevalence and determinants of sudden vision loss (SVL) are unknown in African Americans (AAs). Since SVL can be cardiovascular disease (CVD)-related and CVD is highly prevalent in AAs, we examined the prevalence of and CVD factors related to self-reported SVL lasting 24 hours or longer in the cohort of AAs enrolled in the Jackson Heart Study (JHS).

Methods: The study population comprised 5301 participants enrolled from 2000–2004 in the metropolitan area of Jackson, MS, USA. All participants who responded to the question “Have you ever had any sudden loss of vision or blurring, lasting 24 hours or longer?” on the baseline stroke questionnaire were included in the study. We estimated the prevalence of SVL and used regression modeling to identify CVD factors independently related to SVL.

Results: A total of 5262 participants were included, of which 63% (3334/5262) were female. The prevalence of SVL was 3.6% (193/5262) overall (4.4% in females and 2.4% in males), and 8.7% (84/965) in patients with diabetes mellitus. Factors independently related to SVL included coronary heart disease (odds ratio, OR, 1.69, 95% confidence interval, CI, 1.12–2.56), cerebrovascular disease (OR 2.81, 95% CI 1.76–4.47), diabetes (OR 2.85, 95% CI 2.05–3.94), hypertension (OR 1.64, 95% CI 1.09–2.45), female sex (OR 1.82, 95% CI 1.24–2.67), and income less than US$50,000 (OR 2.05, 95% CI 1.28–3.30).

Conclusions: In this cohort of AAs, self-reported SVL lasting 24 hours or longer was highly prevalent in women and those with diabetes and was independently related to sex, CVD, CVD risk factors and household income.  相似文献

目的:探讨中老年人高血压、糖尿病与年龄相关白内障(age-relatedcataract,ARC)危险性之间的关系。方法:采用以医院为基础的病例对照研究方法。病例由45~85岁的360例因患ARC施行白内障手术摘除的患者组成,对照由同期入住相同医院的360例非白内障患者组成,采取1∶1匹配。采用标准调查表对研究对象进行面对面调查,内容包括人口学特征、生活方式、疾病既往史等,同时对血压、血糖进行测量。应用多因素Logistic回归分析估计高血压及糖尿病与ARC关联的比值比(OR)及其相应的95%可信区间(CI)。结果:在调整了年龄和性别因素后,高血压与ARC呈显著正相关(OR=1.573,P=0.005)。与收缩压正常者相比较,收缩压≥180mmHg者发病的危险性增加(OR=2.812,95%CI:1.450~5.455,P=0.002)。高血压病程10a~的研究对象发病的危险性显著地高于病程〈10a者(OR=1.867,95%CI:1.053~3.307,P=0.033)。同样,与非糖尿病患者相比,糖尿病患者发生ARC的危险性显著升高(OR=2.151,95%CI:1.470~3.149,P〈0.001)。与非糖尿病患者相比,糖尿病病程〈10a和10~19a者发生ARC的OR分别为2.374(95%CI:1.502~3.752,P〈0.001)和2.683(95%CI:1.267~5.683,P=0.010)。结论:ARC患病率增高与高血压、糖尿病及其病程增加有关。对这些可变危险因素采取干预性措施,尤其是对高危人群,可能意味着对ARC导致的视觉障碍必须采取控制性措施,因为此症是全球致盲的首要原因。  相似文献
